在做商城和订单管理的时候,常常会用到分页功能,所以我封装了一个jQuery的分页插件,该插件主要实现上下翻页,输入数字跳转等功能。
具体实现如下:
输入参数需要当前页码pageNo,总页码totalPage,回调函数callback。
主要的实现有两个函数,一个是根据当前页和总页数生成相应的html的代码,一个是事件绑定及回调函数的执行。
creatHtml函数:
- creatHtml:function(){
- var me=this;
- var content="";
- //当前页码
- var current=me.options.pageNo;
- //总页码
- var total=me.options.totalPage;
- //当前页码大于1显示向上翻页按钮
- if(current > 1){
- content += "<a><</a>";
- }
- //总页数大于7,根据当前页显示省略号,否则显示全部页码
- if(total > 7){
- if(current < 4){
- for(var i=1;i<7;i++){
- if(current==i){
- content += "<a class='current'>"+i+"</a>";
- }else{
- content += "<a>"+i+"</a>";
- }
- }
- content += "...";
- content += "<a>"+total+"</a>";
- }else{
- if(current < total - 3){
- content += "<a name='1' type='button' class='page num'>1</a>";
- content += "...";
- for(var i=current-2;i<current+3;i++){
- if(current==i){
- content += "<a class='current'>"+i+"</a>";
- }else{
- content += "<a>"+i+"</a>";
- }
- }
- content += "...";
- content += "<a>"+total+"</a>";
- }else{
- content += "<a>1</a>";
- content += "...";
- for(var i=total-5;i<total+1;i++){
- if(current==i){
- content += "<a class='current'>"+i+"</a>";
- }else{
- content += "<a>"+i+"</a>";
- }
- }
- }
- }
- }else{
- for(var i=1;i<total+1;i++){
- if(current==i){
- content += "<a class='current'>"+i+"</a>";
- }else{
- content += "<a>"+i+"</a>";
- }
- }
- }
- //当前页小于总页数,显示向下翻页按钮
- if(current < total){
- content += "<a>></a>";
- }
- //输入跳转
- content += " 到第 ";
- content += "<input max='3' maxlength='3' value='"+current+"' type='text' />";
- content += " 页 ";
- content += "<a>Go</a>";
- //更新HTML
- me.element.html(content);
- }
bindEvent函数:
- bindEvent:function(){
- var me=this;
- //分页点击事件
- me.element.on('click','a',function(){
- var num=$(this).html();
- if(num=="<"){//上翻
- me.options.pageNo=+me.options.pageNo-1;
- }else if(num==">"){//下翻
- me.options.pageNo=+me.options.pageNo+1;
- }else if(num=="Go"){//输入页码跳转
- var ipt=+me.element.find('input').val();
- if(ipt&&ipt<=me.options.totalPage&&ipt!=me.options.pageNo){
- me.options.pageNo=ipt;
- }
- }else{//直接跳转
- me.options.pageNo=+num;
- }
- //更新html
- me.creatHtml();
- //调用回调函数,返回当前页码
- if(me.options.callback){
- me.options.callback(me.options.pageNo);
- }
- });
- }
将函数封装起来,完整如下:
- ;(function($,window,document,undefined){
- var initDate={
- pageNo:1,
- totalPage:1,
- callback:function(){}
- };
- function Paging(element,options){
- this.element = element;
- this.options=options=$.extend(initDate,options||{});
- this.init();
- }
- Paging.prototype={
- constructor:Paging,
- init:function(){
- this.creatHtml();
- this.bindEvent();
- },
- creatHtml:function(){
- var me=this;
- var content="";
- var current=me.options.pageNo;
- var total=me.options.totalPage;
- if(current > 1){
- content += "<a><</a>";
- }
- if(total > 7){
- if(current < 4){
- for(var i=1;i<7;i++){
- if(current==i){
- content += "<a class='current'>"+i+"</a>";
- }else{
- content += "<a>"+i+"</a>";
- }
- }
- content += "...";
- content += "<a>"+total+"</a>";
- }else{
- if(current < total - 3){
- content += "<a name='1' type='button' class='page num'>1</a>";
- content += "...";
- for(var i=current-2;i<current+3;i++){
- if(current==i){
- content += "<a class='current'>"+i+"</a>";
- }else{
- content += "<a>"+i+"</a>";
- }
- }
- content += "...";
- content += "<a>"+total+"</a>";
- }else{
- content += "<a>1</a>";
- content += "...";
- for(var i=total-5;i<total+1;i++){
- if(current==i){
- content += "<a class='current'>"+i+"</a>";
- }else{
- content += "<a>"+i+"</a>";
- }
- }
- }
- }
- }else{
- for(var i=1;i<total+1;i++){
- if(current==i){
- content += "<a class='current'>"+i+"</a>";
- }else{
- content += "<a>"+i+"</a>";
- }
- }
- }
- if(current < total){
- content += "<a>></a>";
- }
- content += " 到第 ";
- content += "<input max='3' maxlength='3' value='"+current+"' type='text' />";
- content += " 页 ";
- content += "<a>Go</a>";
- me.element.html(content);
- },
- bindEvent:function(){
- var me=this;
- me.element.on('click','a',function(){
- var num=$(this).html();
- if(num=="<"){
- me.options.pageNo=+me.options.pageNo-1;
- }else if(num==">"){
- me.options.pageNo=+me.options.pageNo+1;
- }else if(num=="Go"){
- var ipt=+me.element.find('input').val();
- if(ipt&&ipt<=me.options.totalPage&&ipt!=me.options.pageNo){
- me.options.pageNo=ipt;
- }
- }else{
- me.options.pageNo=+num;
- }
- me.creatHtml();
- if(me.options.callback){
- me.options.callback(me.options.pageNo);
- }
- });
- }
- };
- $.fn.paging=function(options){
- options=$.extend(initDate,options||{});
- return new Paging($(this),options);
- }
- })(jQuery,window,document);
HTML:
<div id="page"></div>
js引用:
- $('#page').paging({pageNo:2,totalPage:10,callback:function(cur){
- console.log(‘当前页:'+cur);//当前页:2
- }});
这里加了一些简单的样式,可以根据具体的ui设计来设计样式。
- <style type="text/css">
- a{
- width: 23px;
- height: 23px;
- border: 1px solid #dce0e0;
- text-align: center;
- margin: 0 4px;
- cursor: pointer;
- display: inline-block;
- }
- .current{
- background-color: #5ac3e7;
- }
- </style>
